KEYBOARD.

Application filed August 2, 1999.

To all W]! 0/11 it In (17/ 0011mm:

Be it known that I, CHARLES citizen of the United States, and a resident of the city of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful improve-- ments in Keyboards; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to that class of key boards adapted for use in connection with cash registers or the like of that class set forth in my prior applications for patent, for total adding cash registers, filed De cember 29, 1908, Serial No. 350,057; and cash registers, filed March 20, 1909. rial No. 484,649, and in which a plurality of co-axial shafts each appropriated to a particular denomination of money are each provided with a dial carrying keys, each marked consecutively with the digit of that denomination, and in which the count is effected by the rotation of the dial and from its normal position of rest to an extent corresponding with the integer of the denomination to be counteth that is to say, any of the integers marked on the keys of the dial, if moved to a stop position common for all the keys would necessitate a rotation of its shaft such as will produce the count or registration of a number corres 'ionding with the integer. In mechanisms for this purpose heretofore devised it has been difficult if the wrong key be engaged to release the same to insure the proper count inasmuch as the inward pressing of the key has served in some instances to engage and operate certain parts of the mechanism, as, for in stance, in some cases in the accumulating from a. lower denomination to a higher. Furthermore, in previous constructions, having pressed a key inwardly to its limit, it has been impossible to quickly restore the same to its normal position and to engage another key in operating position without endangering the accuracy of the count or possibly endangering the accuracy of the machine. This is particularly the case when an error is made by the operator in en gaging the Wrong key and in other machines SULFnn, a

it has been necessary before the key may be returned to normal to actuate the no-sale key and sometimes to operate a set back lever, dependent upon the type of machine.

The object of this invention is to afford a mechanism in which the keys, as such, actuate no mechanism and are, in fact, idlers and which are so arranged that should any key require release after having once been actuated or engaged, it may be instantly accomplished by engaging any other key on the same dial, thus restoring the key first engaged to normal and enabling the machine to be operated independently of such improper or erroneous adjustment and without endangering the accuracy of the count.

It is also an object of the invention to a ford a construction in which any number of dials may be operated simultaneously by means of a single actuating lever and in which the count, if upon one or all the dials, is determined by the adjustment of the particular keys, each in itself Wholly unconnected with the register mechanisms.

The particular mechanism of the register accumulating means, etc., form no part of this invention and are the same as set forth in my prior applications for patents hereinbef ore enumerated and for that reason are not explained or illustrated in detail.

The invention consists in the matters hereina' ter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a central, vertical section taken longitudinally of the shaft with the keyboards in side elevation. Fig. 2 is a front elevation of the machine embodying my invention. Fig. 3 is an enlarged front elevation of a key board dial embodying my invention, showing the same partly in section, and removed from the machine. Fig. 4 is an enlarged, fragmentary detail section illustrating the cooperation of the keys and the actuating lever. Fig. 5 is a fragmentary rear elevation illustrating the spring which acts to return the dials to normal after each actuation. Fig. (3 is an enlarged fragmentary section of one of the dials and the shifting ring, showing one of the release keys in elevation. Figs. 7 and 8 are fragmentary sections of the dial and shifting ring similar to that shown in Fig. 6, but illustrate the cooperation of the keys and shifting ring whereby the engagement by one key serves as a release for all the other keys engaged on the shifting ring. Fig. 9 is an enlarged detail in transverse section illustrating the release for the sh fting ring at the limit of movement of the dials in counting. Figs. 10 and 11 are enlarged fragmentary details of the release mechanism for the keys. Fig. 12 is an enlarged fragmentary detail of one of the key stems.

As shown in the drawings: 1, indicates a cash register of a kind or type adapted to be actuated or operated by a dial key board embodying this invention, and, as shown, embraces a comparatively short tubular shaft 2, and through which extends a tubular shaft 3, of greater length, through which extends a tubular shaft 4, longer than the shaft 3, and through which extends a shaft 5, on which all the before mentioned shafts are ournaled and which at its inner end is journaled in suitable bearings on the opp ite side of the cash register frame. Said shafts are journaled co-axially one upon another and all upon the shaft 5, and, as shown, said shaft 5, is provided at its outer end with a crank or handle 6, rigidly secured thereto whereby it and all the respective shafts hereinbcfore mentioned are rotated as hereinafter described. Each of said shafts 2, 3, and 4, are returned to normal position after actuation thereof by means of a spring 60, which connected with the respective shaft by means of gears (if and 61?.

Secured on the short outer shaft 2, is a metallic plate 7, of considerable d ameter and near the periphery of which is provided a peripheral chamber extending around the same and indicated by S, and the walls of which are raised from the face on said plate. In a similar manner a plate or dial 9, is rigidly secured on the outer end of the shaft 3, and on its periphery is provided with a circumferential chamber 10, as shown in Fig. 4, and in the same i'nanner a plate 11, is secured on the shaft 4, and provided with a peripheral chamber or casing 12. As shown also, a sleeved filler plate 13, is secured on the shaft 5, to close the space between the shaft and the chamber 12, as shown in Fig. 4, and fitted on said shaft by means of a sleeve 14, is a bracket 15, which extends downwardly and is screwed or otherwise secured to the face of the machine, as shown in Figs. 1 and 2, and affords a stop to limit the movement of the dials in counting.

In each of the peripheral chambers on the respective dials is provided a shifting ring indicated by 16. 17, and 18 respectively. These are rotatably supported within the respective chambers out of contact with the side Walls thereof, by means of rods 52, se-

cured to the walls of each chamber on which are secured sleeves 5354, provided with flanges 55 56, between wnich the edge of the rings rotatably engage. As shown, three of said supports are provided on each side of each ring. The outer wall or face of each of said chambers is provided with apertures, as shown rectangular in form arranged equal distances apart on the respective dials dependent upon the travel necessary to produce a sufficient par ial rotation of the shaft to register a digit of the denomination to be counted or registered. Secured on the inner side of said outer wall in register with the aperture therein, are substantially rectangular sleeves 19, which extend inwardly therefrom and into proX- imity with the respective shifting rings and in which are slidably engaged the keys, whereby the count is recorded and which are indicated by the respective digit or characters marked on the face thereof, as shown in Fig. 2. Those on the outer dial 8, indicate pennies or cents-the intermediate dial, dimes, and the inner dial, dollars, and are numbered consecutively, the outer two consecutively from one (1) to 9, and from 10 to 90 inclusive, and the inner or that for the dollar, as shown, numbered from 1 to 5, or more inclusive, to indicate the number of dollars to be counted thereby. Said keys are appropriated (as indicated) to the respective denominations and amounts of money indicated. thereon and to be registered thereby. Said keys each comprise a substantially rectangular stem 20, which extends through the slee e 19, and is tapered at its lower end affording a lower inclined face 58, and upwardly inclined face 59. the top of which is a shouldered notch so that when said end is projected through a suitable aperture in the shifting ring. said ring engages in the notch to ho d the key inwardly. as illustrated in the dimes key on Fig. 4;. By this construction of the key. it is noted that the lower shoulder 57. is of less width than the upper shoulder 60, which adapts any key to release any other kev that has been depressed by mistake. Also, this construction adapts the keys to elliciently operat. even though they wear unevenly which is of considerable importance. Each of said keys is engaged by a spring, as shown in Figs. 7 and 8, which also engages the dial plate and acts at all times to hold the key in its elevated position except when engaged on the shifting ring. The keys also are provided each with a notch, which. when the keys are in their normal position lie outside of the dial. as shown in the dollars and cents keys in Fig. l, and as shown, the actuating lever 6, is provided with a series of inwardly extending hooked brackets 21, 22 and 23, arranged thereon respectively in position one to engage any of the dollar keys, another any of the dimes keys and the last and outermost any of the cents keys when said key is depressed, but which can engage none of the keys otherwise owing to the notch in the side of the key, which permits the hooked end of the bracket to pass therethrough without contact.

Each of the shifting rings is provided with a light spiral or other spring 24, engaged thereto and to a suitable projection 51, on the wall of the respective dials and which acts at all times to hold said shifting ring toward the inward limit of adjustment in position to be engaged in the notches in said keys when the end of the key is projected therethrough. On each of said dials, as shown in Fig. 2, is provided a release key which is marked with the work Release thereon. Each of these, as indicated by 25, is provided with a tapered end, which, however, is not notched, as shown in Fig. (3, and as shown also, the outermost or penny dial is provided with a no sale key 26, adapted to be actuated when it is desired to open the money drawer 27, but the connections for which are not shown in the drawing or described in the specification inasmuch as the same form no part of this invention. A release mechanism is provided on each dial adapted to actuate the shifting ring reversely to release the key previously depressed. or this purpose, as shown, a lever 33, is pivotally engaged on the dial behind the shifting ring and projects through a slot in the shifting ring, as shown in Figs. 3, 10 and 11, and also extends through a slot 34, in the face of the dial.

Fulcrumed on the outside of the shifting ring is a detent lever 35, having its end 36, upwardly curved and adapted to hear at all times on a transverse pin or bar 37. As shown, a tooth or finger 38, integral with said detent lever is adapted to engage in a suitable aperture in the corresponding shift ing ring to hold said shifting ring rigidly fixed with reference to the dial and the mechanism carried therewith.

shown, a spring 39, is engaged on the lever 33, and bears on the detent lever 35, to hold the same at all times in position to engage the shifting ring when the aperture is brought in register With the tooth on said detent lever, and as shown, a. transverse bar or pin 69, extends through the walls of each dial and atl'ords connection for one end of a spiral spring 40, the other end of which is engaged on the lever 33. Said spring acts at all times normally to pull the lever 33, in a direction opposite from its rotation when manually actuated.

The operation is as follows: When it is desired to register a purchase the proper keys are pressed inwardly. is, for instance. $4.65, the 4-, on the inner dial. the G0 on the intermediate, and the 5, on the outer dial will be pressed inwardly until the ends of the respective keys engage in the respective shifting rings, as shown in Fig. 8. In this position obviously the brackets 21, 22 and 255, will weep past all the keys on the dial excepting that indicating $4.00 on the inner, cents on the intermediate and 5 on the outer which will be brought by said brackets into alinement and as said lever is swung about to the limit of its downward position, said keys are brought down to the stop bar 15. at which point each shaft has actuated the appropriate mechanism to atl'ord the register or count. hen the handle is released springs engaged on the respective shafts or on the dials (as the case may be) act to pull said dials back to normal, and as shown, the spring 30, secured n the end plate 31, of the cash register and on the shaft 5, acts immediately to return the crank to normal or to the position shown in Fig. 2, ready for another count. It is important, of course, to immedately release the previously depressed key after the count has been effected and thus to set the machine for the next succeeding count. This accomplished by means of the release mechanism operated by the levers 33. These levers under the action of their springs 40, tend to pull the detent 35, into position to engage and hold the shifting ring during the forward or registering movement of the dial, as indicated in Fig. 10. hcn the count has been efl'ec ed, however, and the dials have returned neaily to their normal position the outer end of the levers 33. engage the bar or plate to, as shown in Fig. it), and the continued rotation of the dial on which said lever is fulcrumed acts to crowd the dctcut bar forwardly over the pin or bar 5'27, thereby. (owing to the end of said dctent l ar being inclined upwardly) lifting the lingn' 5%, out of the notch in the shifting ring and permitting the ring to rotate forwardly under the pull of its spring 24. The initial forward movement of the shifting ring prior to the release thereof by the detent sufficient to release the notched ends of the key stem from the shifting ring, permitting the keys to return to normal so that when the dials come to rest in the position shown in Fig. 2, and with the release mechanism as shown in Fig. 11, all the keys are retracted to their normal position and the machine is again ready for use.

By means of the construction hereinbefore described it obvious that. should the wrong key be depressed on any dial by accident or error, it may be instantly released by depressing the appropriate key on the same dial or by pressing the release key on said dial, thus aii'ording a facility in rectifying errors not hcretolorc so easily attainable in cash registers. Obviously, one or any number of the dials may be actuated simultaneously in counting, and, of course, while I have shown but five significant digits on the dollar dial, it is to be understood that a greater or less number may be indicated if preferred.

Of course, the particular construction may be varied in many respects. I therefore do not desire nor purpose limiting the patent issued, otherwise than necessitated by the prior art.
